Multi-soliton interaction of nonlinear ion sound waves in a pair-ion–electron (PIE) plasma having non-Maxwellian electrons including Kappa, Cairns, and generalized two spectral index distribution functions is studied. To this end, modified Korteweg–de Vries (mKdV) equation obtained to investigate the ion-acoustic PIE at critical composition. The effects temperature density ratios electron velocity distributions on overtaking solitons are explored detail. results reveal that both hump...

Linear and nonlinear acoustic drift waves in a confined inhomogeneous dusty plasma are investigated here. We examine two distinct scenarios that correspond to slow fast temporal dynamics. The dust particles inert the first scenario, but actively participate dynamics second. Accordingly, we distinguish between coupled dust-modified ion-acoustic ultra-low-frequency waves. corresponding dispersion relations were determined both situations by using linear analysis. In addition, coherent...

The observations of the magnetospheric multiscale (MMS) and Cassini Huygen's missions report presence cold hot populations electrons, which lead to generation electron-acoustic waves. observed electron velocity distributions from these demonstrate that particles do not follow Maxwellian distribution, exhibit distinct characteristics, can be effectively accounted for by other non-Maxwellian distributions.
